[0032] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] The following describes the specific implementation of the present invention in detail with reference to specific embodiments:

[0034] Example 1:

[0035] Figure 1A The implementation process of the service data transmission method provided in Embodiment 1 of the present invention is shown. For the convenience of description, only the parts related to Embodiment 1 of the present invention are shown and are described in detail as follows:

[0036] In step S101, the quality of service information of each user equipment when establishing a bearer is obtained.

[0037] The embodiments of the present invention are applicable to the base station side. The user equipment (UE) in the examples of the present invention may be devices such as mobile phones, tablet computers, wearable devices, in-vehicle devices, laptop computers, AI (Artificial Intelligence) devices, industrial sensors, etc. The embodiments of the present invention do not impose any restrictions on the specific types of user equipment.

[0038] In the embodiments of the present invention, during the process of the user equipment establishing a service bearer, the base station BBU (Base Station Processing Unit) can obtain the quality of service information of each user equipment when establishing the bearer, so as to classify the services with QoS requirements through the quality of service information. Preferably, the quality of service information is the 5th generation quality of service identifier 5QI, so as to classify the services with QoS requirements through 5QI.

[0039] In step S102, the service data of all user equipment is classified based on the quality of service information, and the service data with the first quality of service requirement and the service data with the second quality of service requirement are obtained.

[0040] In the embodiments of the present invention, the services with the first quality of service requirement are services of the same level, and the services with the second quality of service requirement are services of the same level. The first quality of service requirement and the second quality of service requirement can be understood as two different levels of service data. As an example, as Figure 1B shown, there are N user equipments accessing the base station cell, namely UE1 to UEN. Services 1 with the same QoS requirements of multiple UEs are transmitted on carrier 1, and services 2 with the same QoS requirements of multiple UEs are transmitted on carrier 2.

[0041] In step S103, the service data with the first quality of service requirement is transmitted on the first carrier, and the service data with the second quality of service requirement is transmitted on the second carrier.

[0042] In the embodiments of the present invention, the first carrier is used to transmit the service data with the first quality of service requirement, and the second carrier is used to transmit the service data with the second quality of service requirement. The air interface parameters of the first carrier and the second carrier are different. Therefore, within a single carrier, all services have the same QoS requirements, which can ensure the same scheduling priority of different services on the radio air interface and can meet the low-latency characteristics or high-bandwidth and high-reliability characteristics of the services.

[0043] Before transmitting the service data with the first quality of service requirement on the first carrier, preferably, the maximum number of carriers of the first carrier and the second carrier are respectively configured to meet the actual transmission requirements of the service data.

[0044] Before transmitting the service data with the first quality of service (QoS) requirement on the first carrier, preferably, configure the first radio access network (RAN) parameters for the first carrier based on the first QoS requirement, and configure the second RAN parameters for the second carrier based on the second QoS requirement, so as to configure different RAN parameters according to different service transmission requirements. Among them, the first RAN parameters are different from the second RAN parameters. Further preferably, the service data with the first QoS requirement is low-latency service data, and the service data with the second QoS requirement is high-reliability service data with large bandwidth. When configuring the first RAN parameters for the first carrier, configure a conservative automatic modulation and coding (AMC) strategy for the first carrier. When configuring the second RAN parameters for the second carrier, configure a conservative scheduling strategy for the second carrier, so as to meet the transmission requirements of both low-latency services and high-reliability services with large bandwidth at the same time. Specifically, for low-latency services, a conservative AMC strategy can be configured through uplink pre-scheduling; for high-reliability services with large bandwidth, conservative scheduling can be configured to reduce the target block error rate (Bler), enable the active retransmission mechanism, and perform active hybrid automatic repeat request (HARQ) retransmission through transmission time interval bundling (TTI bunding) or slot aggregation, to ensure reliable data transmission. Among them, the transmission time interval is abbreviated as TTI.

[0045] In the embodiment of the present invention, obtain the QoS information of each user equipment when establishing a bearer, classify the service data of all user equipments based on the QoS information, obtain the service data with the first QoS requirement and the service data with the second QoS requirement, transmit the service data with the first QoS requirement on the first carrier, and transmit the service data with the second QoS requirement on the second carrier. Thus, by transmitting the service data with different QoS requirements on different carriers respectively, the independence of the service transmission with different QoS requirements is ensured, and the service data with different QoS requirements carried on the 5G private network can meet the corresponding service transmission requirements.

[0046] Example 2:

[0047] Figure 2 The structure of the service data transmission device provided in the second embodiment of the present invention is shown. For the sake of convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0049] A service classification unit 22, configured to classify service data of a user equipment based on service quality information, so as to obtain service data with a first service quality requirement and service data with a second service quality requirement; and

[0050] A service transmission unit 23, configured to transmit the service data with the first service quality requirement on a first carrier, and transmit the service data with the second service quality requirement on a second carrier.

[0051] In an embodiment of the present invention, during the process of establishing a service bearer for a user equipment, a base station BBU (unit to be processed urgently) can obtain service quality information of each user equipment when establishing the bearer, so as to classify services with QoS requirements through the service quality information. Preferably, the service quality information is a fifth-generation service quality identifier 5QI, so as to classify services with QoS requirements through 5QI.

[0052] Services with the first service quality requirement are services of the same level, and services meeting the second service quality requirement are services of the same level. The first service quality requirement and the second service quality requirement can be understood as two different levels of service data.

[0053] The first carrier is used to transmit service data with the first service quality requirement, and the second carrier is used to transmit service data with the second service quality requirement. The air interface parameters of the first carrier and the second carrier are different. Therefore, within a single carrier, services have the same QoS requirements, which can ensure the same scheduling priority of different services on the radio air interface, and can meet the low-latency characteristics or the large-bandwidth and high-reliability characteristics of services.

[0054] Preferably, the apparatus further includes a carrier number configuration unit, configured to respectively configure the maximum number of carriers of the first carrier and the second carrier, so as to meet the actual transmission requirements of service data.

[0055] Preferably, the device further includes an air interface parameter configuration unit, which is configured to configure first air interface parameters for a first carrier based on a first quality of service requirement, and configure second air interface parameters for a second carrier based on a second quality of service requirement, so as to configure different air interface parameters based on different service transmission requirements. Among them, the first air interface parameters are different from the second air interface parameters. Further preferably, the service data of the first quality of service requirement is low-latency service data, and the service data of the second quality of service requirement is high-reliability service data with large bandwidth. The air interface parameter configuration unit is further configured to configure a conservative AMC policy for the first carrier and a conservative scheduling policy for the second carrier, so as to simultaneously meet the transmission requirements of low-latency services and high-reliability services with large bandwidth. Specifically, for low-latency services, a conservative AMC policy can be configured through uplink pre-scheduling; for high-reliability services with large bandwidth, conservative scheduling can be configured to reduce the target Bler (block error rate), enable the active retransmission mechanism, and perform active hybrid automatic repeat request (HARQ) retransmission through transmission time interval bundling (TTI bunding) or slot aggregation, to ensure the reliable transmission of data. Among them, the Transmission Time Interval is abbreviated as TTI.

The information acquisition unit is configured to acquire the quality of service information of the user equipment when establishing a bearer. The service classification unit is configured to classify the service data of the user equipment based on the quality of service information, so as to obtain service data with a first quality of service requirement and service data with a second quality of service requirement. The service transmission unit is configured to transmit the service data with the first quality of service requirement on the first carrier and transmit the service data with the second quality of service requirement on the second carrier. Thus, by transmitting service data with different QoS requirements on different carriers respectively, the independence of service transmission with different QoS requirements is ensured, and the service data with different QoS requirements carried on the 5G private network can meet the corresponding service transmission requirements.
